Sea-Dog Fast Eye Boat Snap #3, 3-13/16 Inch Sand Cast Brass Spring-Loaded Rigging Snap

The Sea-Dog Fast Eye Boat Snap #3 (part number 139123-1) is a spring-loaded rigging snap built for medium duty marine use. It is constructed of sand cast brass with a polished finish, giving it a functional, corrosion-resistant build that also looks decorative on deck hardware, rigging, or gear attachment points. The spring-loaded latch opens easily for one-handed attachment and closes securely to hold its grip under everyday rigging loads.

This #3 size snap measures 3-13/16 inches overall, with a 9/16 inch and 3/4 inch dimension at the eye and opening. It is commonly used for tethers, paddle leashes, and other light-to-medium duty rigging tasks where a dependable, quick-attach brass snap is needed. The fast eye design (a fixed, non-swiveling eye) makes it a straightforward choice anywhere a swivel action is not required.
